Finally completed the job, which included new brake ducts and the holes to feed them. I had a ranger airdam on it which worked, but looked ugly, and when the ducts got damaged and worn out, I decided to try the Mach 1. It fit pretty good, I just had to slit the backing in two places so I could bend the fender extensions in to fit the fenderline without wrinkling it. I think it turned out pretty clean.
I used 4-inch-to-3-inch galvanized reducers bent down square at the large end for the scoops:
Passenger side ducting:
I closed the gap between the duct and the dam with aluminum tape, then painted it. Looks like ass but few people will see it
Drivers side ducting:
